Genera 11, species ca. 160 (2 genera, 7 species in the flora).
Species of Halesia and Styrax are sometimes cultivated for ornament, and species of Alniphyllum, Melliodendron, Pterostyrax, Rehderodendron, and Sinojackia have been successfully grown in the United States.
About 80% of the species of Styracaceae belong to Styrax; the next largest genera in the family are Rehderodendron and Sinojackia, with five and six species, respectively. All genera are endemic to eastern and/or southeastern Asia with the exception of the two in the flora.
The Styracaceae have been shown to be monophyletic on the basis of morphological and DNA sequence evidence (P. W. Fritsch et al. 2001). Studies with DNA sequence data place Styracaceae within order Ericales (in the sense of Angiosperm Phylogeny Group 2003; C. M. Morton et al. 1996; A. A. Anderberg et al. 2002) as sister to Diapensiaceae, and Styracaceae + Diapensiaceae are sister to Symplocaceae (J. Schönenberger et al. 2005). The South American genus Pamphilia is now included within Styrax (B. Wallnöfer 1997; Fritsch 1999, 2001).
The fossil record of the Styracaceae extends back to the early Eocene (B. H. Tiffney 1985).
In the present treatment, calyx dimensions include the hypanthium, whereas those of the corolla and stamens do not. Leaf dimensions are those of the larger examples on each specimen except where noted.
